The Microchip Technology Inc. 24AA32A/24LC32A  
(24XX32A*) is a 32 Kbit Electrically Erasable PROM.  
The device is organized as a single block of 4K x 8-bit  
memory with a 2-wire serial interface. Low-voltage  
design permits operation down to 1.7V, with standby  
and active currents of only 1 μA and 1 mA,  
respectively. It has been developed for advanced, low-  
power applications such as personal communications  
or data acquisition. The 24XX32A also has a page write  
capability for up to 32 bytes of data. Functional address  
lines allow up to eight devices on the same bus, for up  
to 256 Kbits address space. The 24XX32A is available  
in the standard 8-pin PDIP, surface mount SOIC,  
TSSOP, DFN, TDFN and MSOP packages. The  
24XX32A is also available in the 5-lead SOT-23  
package.
